That would work out very well. It is a 'free ebook up sell' technique which a lot of people in the dating and seduction community uses. Give out a free ebook on '10 Secrets to win her over' and then you have a few product mentioned in the free book.
A note on the journey:
A Web 2.0 you can reregister that no one talks about is Web Node. Why? They are harder to get because you can register one and not use it, so traditional Web 2.0 methods sometimes give false positives.
Because of this they are not as picked through as other expired Web 2.0s. You can't buy these because they are harder to get a hold of, and they tend to be weaker than other Web 2.0s.
Why mention this?
If you are new to SEO and need to practice and want an easier time to scrape Web 2.0s then you should consider Web Nodes. I am using them to Replace Weeblys because Weebly requires you to pay for indexing now. My older Weebly accounts are fine but I can't use new ones, so I needed a new idea.
You also want to diversify a bit and not only use Tumblrs to rank.
I am at the part of this journey where I made enough to start a PBN, so I will be going through all that jazz. I used some of the profits to pay someone else to find domains as I was sick of my methods from finding these Web 2.0s. I ran into a problem with a few sellers. Now that I have more experience in IM, most of the domains sold do not make the cut. This is for BHW, Fiverr, Source Market, ect. People who sell domains often over look:
1. Back Links profile history (You need to compare launches of sites with web archives to see if anything looks like spam durig dates when major changes or additions happened to the site.
2. High metrics does not mean it is a solid domain.
This one irks me quite a bit. We all know your domain has 25 TF, 25 PA, 25 DA, and 30 CF plus a PR 3 so it sells for $75. But when you get one of these domains and look at the back link profile you find the TF is spiked because the site has 2 high TF links which are blog comments on a spam site. It has high DA because the domain has a good number of links from high OBL 'links to our partners' pages which is featured with 100's of other sites. Lastly the high PA is because it has a couple site wide links from spam domains.
The stats are pumped up high but the domain has horrible back links and thus is a bad domain. I would not link that type of domain to my money site.
So be careful when out sourcing finding domains. I suggest you find them yourself because you get the best domains possible. If I am going to drop 10 for the registration, 50 for content and 30 for a premium theme plus hosting, I want to make sure I have an amazing domain.
